Title: Cam for TBI
Post by: Unofficial on May 07, 2013, 08:41:20 am

Hey guys, I'm looking to get a new cam for my '87 350 tbi engine.  I'm not looking for a ton of performance, just something that won't screw up my MAP sensor because of vacuum problems that come along with too much duration.  I've read that for tbi, you shouldn't go over 218° @ .050 but I wonder if I need to know even more.  I noticed that some of them say "computer controlled compatible," is that something required for this set up?

I have a summit cam in right now but I believe I'm having issues with the gear for the distributor so I'd like to pull it out.

Thanks for any info and let me know if you need more details to help me out

I don't have tbi, but I have the comp cams 260h and love it for a daily cam.  Great vac check my first vid. https://www.youtube.com/watch?v=vehbMQSlcSw&feature=youtube_gdata_player

Most of the bigger brand name camshaft companies have detailed information on compatibility. Staying in the the low 200's @ .050 in duration should give you some nice torque.
